My invention relates to car loading appliances in general and concerns more specifically Structures for loading pit-cars of mines.

In the mining of coal, it is customary to deliver it into a stationary pit-car capable of travelling on suitable rails and the base or truck portion of the loading apparatus is designed to rest on the same rails and of course to travel thereon when moved from one loca tion to another.

The main object and purpose of the present invention is to provide a. loading appliance which, while bearing on such rails, can be shifted angularly in substantial measure so that the coal may be delivered into the car over a comparatively wide range of receiving points, the apparatus being so constructed that its position or angular disposition may be varied as occasion requires without substantial interference with the supporting pillars or posts in the general location where the loading is to occur.

To the attainment of this and other desirable objects, I have devised the novel invention, a present preferred embodiment of which is illustrated in the accompanying drawings, forming a. part of this specification and throughout the several views of which like reference characters have been employed to designate the same parts.

In these drawings Figure 1 is an elevation of the apparatus;

Figure 2 is a cross section through the same on a larger scale on line 2 2;

Figure 3 is a plan View of the structure; and

Figure 4 is a detailed view of the expansible and contractible trackway supporting the conveyer.

Referring to these drawings, it will be noted that the lower truck portion of the loa-der comprises a suitable truck-frame 11 equipped with flanged wheels 12, 12 adapted to bear and to travel on the same rails 13, 13 as accommodate the pit-car, not shown, whereby the appliance as a whole may be caused t o travel on such rails, when it is desired to change its location, by means of an electric-motor 14 mounted on the truck-frame and suitably operatively connected, as by a sprocketswheel .and chain mechanism 15, 'to oneof the truck axles, thus permitting the loader to move itself along the rails under lits own power a's occasion demands.

On the depressed truck-frame', between its pairs of wheels, there are xecily mounted a p'air of channel-bar tracks 16, 16 and beside each of vthese there is another companion, slidable, Vchannel-bar track 17,"the backs of the two` channels being toward onea'nother. In order to join the two', supplemental, slidable tracks' together t'ol form a unit, they areeonneoted together inany approved inanner', as by a pair of smaller channel members a The'main track elements 16, 16 are slightly higher'than theauXiliary track members 17, 17, ortliey may-be of the same depth with'the former slightly elevated Vas by shims 26eme ployed beneaththem, sothat the upper lfaces ci the two sets will he a little different.

n An auxiliary truck 19 having doubleiianged carrying-wheels 21, 2i on the track members 16, 16 l17, 117 is adapted no'rn'iallyto be positioned directly'ove'r the center of the underlying er inain truck 1i, 12 as shown in Figure 2, pivoted centrally'on such upper truck at 22 I employ a suitable support 23 pivotally or hingedly carrying at its top 9 the framework, base and sloping sides 24 of an endlessconveyer comprising a pair of end-y less chains, 25, 25 and spaced erosssbar's or slats 26, 26 connecting them together at intervals. v

Such endless -conv'eyer has a lower horizontal section 27 adapted to overlie the 'rails 13, 13, an inclined, 'intermediate portion 28 mounted directly on the support23 and an upper horizontal part 29 designed to extend over the pit-car, whereby coal shovelled on to the part 27 will be automatically carried up and discharged into the car by' the upwardly moving siatso'ithe conveyor, the latter being operated by eleetricanotor and appropi-iate driving connecting ineens in a easing 3i onthe underside ofthe conveyor frame.

When it is desired that the eonveyer1reL ceive the coal from 'a position atene side of the trackway, as indicated in dotted linesin Figure 3, and to deliver yit into the pit-car in 2 the same position as before, it is of course necessary to shift the receiving end of the conveyer to one side of the trackway but to retain its elevated discharge end over the trackway and the pit-car thereon.

This result is accomplished by manually pulling out the united, supplemental, channel rails 17, 17 in the proper direction, it being understood that they may be thus projected from either side of the truck-frame 11,- and for the purpose of supporting their outer ends in their extended relation, each is supplied with a vertically-apertured bracket 32 which receives a transversely-perforated pipe 33, the lower end of which is received in a hollow standard 34 designed to rest on the ground, demountable cross-pins 35, 86 accommodated in such holes supporting the pipe in the standard and supporting the bracket on the pipe.

The crosswise-disposed, extension trackway having been thus properly positioned and sustained at its outer end, the auxiliary truck 19 carrying the conveyer is rolled out on to the channels 17, 17, the conveyer mounting turning, as required, on the pivot pin 22.

If needed or desired, the inner movable rails 17, 17 may be held slidingly in position by means of cli s 10, 10 fastened to the truck frame and overying their lower flanges.

The specified lateral projection of the telescoping trackway is readily accomplished without interference with neighboring or adjacent pillars or posts in the mine chamber, and when its use in this relation terminates, the auxiliary truck can be pushed back into register with the main truck, the supports 33, 34 removed and the supplemental trackway slid back into original position.

From the foregoing it will be apparent that the endless conveyer may be turned to either side of its supporting main truck in the manner-indicated and easily and readily replaced in normal position, thus facilitating the filling of the pit-car by coal fed from different locations on to the properly positioned lower end of the conveyer.

The invention is not limited and restricted to the precise and exact details of structure shown and described and these may be modified within comparatively wide limits without departure from the heart and essence of the invention and without the loss or sacrifice of any of its material benefits or advantages.

I claim:

1. 1n a car-loader, the combination of a main-truck equipped with carrying-wheels, a contractible and extensible trackway mounted on and crosswise of said main-truck, an auxiliary-truck having carrying-wheels on said trackway, and a conveyer pivotallyl mounted on said auxiliary-truck, whereby the angular relation of said conveyer to said main-truck may be varied by changing the position of said auxiliary-truck on said track- Way.

2. In a car-loader, the combination of a main-truck equipped With carrying-Wheels, a telescopic contractible and extensible trackway mounted on said main-truck crosswise thereof, an auxiliary-truck having carryingwheels on said track-way, an endless conveyer structure pivotally mounted on said auxiliary-truck, and means to support the outer end of said trackway in its extended condition, whereby the angular relation of said conveyer to said main-truck may be varied by changing the position of said auxiliarytruck on said trackway.

In witness whereof I have hereunto set my hand.

ROBERT BAUERLE.
